Bog or Stumble off idle

3702 Views 7 Replies 5 Participants Last post by  tjstarduster
I had my Holley 780 rebuilt a few months ago and I've noticed the car has developed somewhat of a bog, or stumble off idle as I'm letting out the clutch. After a second or two, the engine catches and the revs go up.

Any idea what might be causing this? Carb idle mixture screws or accelerator pump?

Check your power valve. I'm guessing you need a 4.5 with a high performance engine.
